Mu Dynamics has raised $10 million and given itself a new name as part of its efforts to locate and fix network vulnerabilities.

The Sunnyvale, Calif. startup was previously called Mu Security, but as of today has renamed itself to emphasize its broader focus. Mu and its product, the Mu-4000 Appliance, aren’t just focused on network security, but on finding any vulnerability that might cause the network to go down.

This funding round — Mu’s third — was led by Focus Ventures, with participation from Accel Partners, Benchmark Capital and DAG Ventures.
